Help Cant connect to 4G LTE on Icon

[zr0w69]

After rooting with kingroot i unrooted then did a factory reset. Phone worked fine until i used a program named elixer 2. After using the network settings i cant connect to the LTE using my hydro. I really need help. I think it wiped my carrier settings or something. I have tried everything I can think of. I called boost and they walked me through the ##72768# and also i have hard reset my phone to factory and still the lte wont work. if you can help me in any ay it would be much appreciated!
